Spare tire for Alaska trip ?

I carry a spare tire, a rated bottle jack and lug tools to change. While I may not feel capable of doing the job myself, at least I am ready to accept help, without getting stranded for a week. While there are services available, scheduling has to be considered. A fellow camper south of Whitehorse a hundred miles was stuck for two weeks last summer waiting on shop time availability and tow truck for a diesel exhaust problem.
